It’s a great suggestion, and if I had any difficulties with dairy other than with coffee, I’d consider it. But I’ve been drinking regular milk all my life with no issues other than rich whole milk or half and half with strong coffee, and I solved that one by drinking it now with reduced fat milk. My issues are with too much fat in the milk combined with the acid in the coffee. By reducing the fat, I can drink my coffee with low fat milk and no problems at all. I’m sure others will benefit from your suggestion, though!
Okay. It’s pretty good. Very rich, and if you prefer a more classic chocolate chip cookie, there are probably better recipes out there. In order to try it as recommended in the recipe – meaning 5 minutes after it comes out of the oven – I had to < wrist to forehead > eat dessert before dinner. The sacrifices I make!
But it’s tasty. Crispy cookie on the outside and soft underneath.
The recipe suggests it makes 4 generous servings. I would amend that to gluttonous. They also suggest serving it with ice cream, which would further raise (lower?) the bar to positively porcine. 
I ate an eighth, sans ice cream, and it is plenty.
Tonight I’ll learn if it freezes well.
Let me know if you want the recipe. It’s dead easy to make. Something quick to throw together for unexpected company.
